Terminology is important in immigration. Using the term "wife" implies marriage. The CO needs only suspicion that a secret marriage has taken place to immediately disqualify a couple from a K-1. It would a shame to get a denial at the interview stage. @JeanneAdil is pretty familiar with MENA countries and their culture.
The only effect will be that you will have to prove you still have domicile in the US or you intend to re-locate back to the US. You also have to show current US based income and/or assets.
That's pretty common. Additional background check after the interview is part of administrative processing. It can take a bit of time to complete the process.
Doesn't sound like a real immigration attorney. Lot of misinformation and lack of vital, basic understanding of the process . Lots! Ask your brother to join us here, and study this guide to become an "A" student of the process:
I see no sign for either approval or otherwise. This is administrative processing. This is a Pakistani case, so the AP could be quite lengthy. Good luck.
Congratulations!!!!!
Sounds like a new officer interviewed you. I'm not sure why she asked you so many citizenship questions. There was no reason to ask 10 questions.
